Over exposed image information recovery via stochastic resonance

摘要: Over exposure is rather annoying in photo taking. However, some severe light conditions over inevitable using conventional cameras due to the limitation of dynamic range image sensor. The exposed information would be completely lost and unrecoverable. In order cope with this problem, we propose a novel technique which noise used enlarge essential mechanism that contributes recovery investigated. It also proved visibility regained can reach peak when specifically added synchronized sensor, thus activating phenomenon stochastic resonance (SR). Four different types noises are investigated show effects variant distributions on quality recovered information. experimental outcomes consistent our theoretical results, indicates SR-based quite promising.
